Chromium complexes multinuclear

Some multinuclear chromium(III) complexes which contain pyridine ligands have been described. The amide (122 - FL,L) reacts with CrCl3-6H20 in pyridine solution containing Na2C03 to give the dimer [Cr2(HL)2(py)4]-2py, the structure of which is described in Section 35.4.2,11.519... 

Multimetallic complexes, molybdenocene dihydrides, 5, 570 Multimetallic nickel-alkynes, synthesis and reactivity, 8, 145 Multinuclear chromium(II) complexes, with halides, alkyls,... 

The aromatic moiety in phenylboranes and phenylb-orates may serve as a 6-electron tt donor ligand to transition-metal complexes. Half-sandwich complexes of chromium, Mes2[B( -Mes)Cr(CO)3] (56), MesB[jj -MesCr(CO)3]2 (57), and B[ -MesCr(CO)3]3 (58), containing trimesitylborane as a ligand have been prepared and structurally characterized. The Cr(CO)3 moieties interact weakly in the multinuclear systems (57) and (58) as shown by...
